The importance of crypto asset custody is still underappreciated across the industry. Beyond safeguarding digital assets for holders, custody services act as a vital bridge between the crypto economy and traditional finance. Recent regulatory breakthroughs have further solidified its legitimacy, paving the way for broader institutional adoption.
Regulatory Tailwinds Fuel Market Growth
In late July, the U.S. Office of the Comptroller of the Currency (OCC) issued a letter clarifying that national banks and federal savings associations may now provide cryptocurrency custody services. This landmark decision creates a more favorable policy environment for traditional financial institutions to enter the space—and signals growing regulatory acceptance.

More importantly, this shift could significantly accelerate institutional investment in digital assets. In traditional capital markets, custodians play a critical role in the chain of “asset management—brokerage—custody—trading—clearing and settlement.” As this framework evolves into the crypto ecosystem, the separation of exchange functions from custody is becoming increasingly clear.
“Only with trusted custodians can traditional financial managers gain the confidence to allocate capital into this emerging asset class,” said Zhang Li (a pseudonym), a business executive at Huobi.
According to the U.S. Investment Advisers Act of 1940, Rule 206(4)-2 mandates that any registered investment adviser deemed to have custody of client assets must hold those assets with a qualified custodian and undergo regular independent audits. For years, most crypto custodians emerged organically within the blockchain ecosystem, while major traditional custodians remained on the sidelines. The OCC’s clarification may finally ease their concerns.
“As financial markets become increasingly digital, banks and service providers must adopt new technologies to meet evolving customer needs,” the OCC stated, reinforcing its view that banks should continue serving as financial intermediaries in payment, lending, and deposit services—even in a decentralized world.
Market Landscape: From Pioneers to Institutional Players
The crypto custody market began taking shape around 2013–2014, with early entrants like Xapo leading the charge. Backed by $40 million in funding, Xapo leveraged first-mover advantage to win trust from institutional clients. By early 2018, it reportedly stored about 7% of all circulating Bitcoin—worth roughly $10 billion at the time.
Other early players included Metaco and Kingdom Trust, which laid foundational infrastructure for secure asset storage. As crypto prices surged and demand grew, major exchanges and wallet providers entered the fray. Coinbase, BitGo, and Cobo launched institutional custody offerings in 2018. The following year saw Gemini, Bakkt, and hardware wallet maker Ledger join the space.
Since 2019, traditional financial institutions have cautiously entered the market. Fidelity Digital Assets and Prime Trust are notable examples, though regulatory uncertainty and high compliance barriers have limited widespread participation.
At the same time, consolidation has accelerated. BitGo acquired Kingdom Trust, Hedge (a staking provider), Harbor (a security token platform), and Lumina (a portfolio management tool). In August 2019, Coinbase acquired Xapo’s institutional custody business for $55 million—boosting its client base to over 150 institutional customers and assets under custody exceeding $7 billion, including more than 225,000 BTC held on behalf of major investors.
Two Distinct Market Segments
Crypto custody services can be broadly categorized into two segments:
- Consumer-grade (To C): Focused on individual users through hardware cold wallets or hot wallets (web/mobile apps), prioritizing ease of use and flexibility.
- Enterprise-grade (To B): Designed for institutions using cold storage, multi-signature setups, and API-driven platforms—emphasizing security, reliability, and comprehensive service support.
Divergent Service Models
Custody solutions also differ in scope:
- Storage-only custody: Clients store assets long-term without frequent withdrawals—ideal for family offices and investment funds.
- Technology-integrated custody: Offers additional technical services such as blockchain address generation and public chain integration. For example, around 40% of Cobo Custody’s clients are exchanges that use its infrastructure to generate user addresses—meaning many exchange addresses are actually powered by Cobo’s backend systems.
Security Mechanisms: HSM, MPC, and Multi-Signature
Different security models cater to varying operational needs:
- HSM (Hardware Security Modules): Physical devices that securely generate and store cryptographic keys.
- MPC (Multi-Party Computation): Splits private keys into fragments across multiple parties; ideal for high-frequency operations due to lower latency.
- Multi-Signature: Requires multiple approvals for transactions; highly secure but slower for urgent withdrawals.
High-security custodians often go further—Coinbase Custody and Xapo store private keys in geographically distributed vaults. Xapo famously converted a decommissioned Swiss military bunker into a secure facility accessible only to personnel with pre-registered biometric data.
“One time we initiated a large transfer, and their team called us via FaceTime to confirm we weren’t under duress,” shared a client in a Fortune interview. “For very large amounts, they flew someone out in person.”
The Road Ahead: Profitability, Expansion, and Risk Mitigation
Despite growing interest, the custody sector faces a fundamental challenge: sustainability.
Currently, most providers generate revenue through flat custody fees (typically basis points of AUM) and transaction charges for fund transfers. However, this model pales in comparison to traditional custodians that offer diversified services like settlement, proxy voting, income collection, and reporting.

“Compared to mature custodial banking models, we’re still in the early innings,” noted Zhang Li. Intensifying competition has driven fees downward, pushing many players into loss-leading strategies in hopes of capturing market share before scaling profitability.
Some firms are innovating beyond pure custody:
- Anchorage, a licensed crypto bank, now offers brokerage services. “Institutional investors want one-stop solutions—custody, trading, staking, governance voting,” said CEO Nathan McCauley. “We aim to be that platform.”
- Others are expanding into lending, asset management execution, and yield-generating strategies.
Addressing Security Risks with Insurance
Even with robust safeguards, no system is immune to breaches. Unlike major exchanges with deep reserves or insurance funds (e.g., SAFU), many custodians lack similar backstops.
This gap has spurred growth in crypto-native insurance products. Global insurance broker Aon has formed a consortium to offer coverage for digital assets held via Metaco. However, premiums remain steep—often ranging from several percent to over 10% annually—based on rigorous security assessments.
“Insurance costs are high because underwriters take security very seriously,” said Cobo’s Li Yao. “They evaluate everything from key storage methods to physical access controls.”
Frequently Asked Questions (FAQ)
Q: Why do institutions need crypto custody instead of self-custody?
A: Institutions require auditable, compliant, and insured solutions that meet fiduciary standards. Self-custody lacks oversight, increases operational risk, and may violate regulatory requirements like SEC Rule 206(4)-2.
Q: What makes institutional custody different from personal wallets?
A: Institutional solutions offer multi-layered security (HSM/MPC/multi-sig), enterprise APIs, integration with accounting systems, audit trails, and often third-party insurance—features absent in consumer wallets.
Q: Can custodians access my assets?
A: Reputable custodians use permissioned architectures where no single entity has full control. Access requires multiple verifications and is logged for audit purposes.
Q: Are there global standards for crypto custody?
A: While no universal standard exists yet, frameworks like NYDFS BitLicense, SOC 2 compliance, and ISO certifications are emerging benchmarks.
Q: How do custody fees compare across providers?
A: Fees vary widely based on service level—basic storage may cost 0.1% annually, while full-service platforms with integrated trading or staking can charge more depending on usage.
Q: Is insured custody completely safe?
A: Insurance mitigates loss risk but doesn’t eliminate it. Coverage limits apply, and claims depend on proof of proper procedures being followed.
